Temperature ranges of a floor heating

The underfloor heating offers undoubtedly many advantages, but there are also disadvantages. But in terms of uniform distribution of room temperature and efficiency, the underfloor heating is far ahead. The underfloor heating ensures even with relatively low flow temperatures for a very pleasant perceived indoor climate.

Underfloor heating - in the new building as well as in the renovation possible

Anyone planning a new building today should think hard about the shape of the heating system. The underfloor heating offers a lot of advantages, especially in new buildings, when no structural changes have to be made to existing buildings. It is of course also possible to retrofit existing buildings with underfloor heating, but in this case a thorough calculation of the cost of use must be made. The underfloor heating offers significant advantages, especially in connection with a heat pump, since it can be operated with a relatively low flow temperature, thereby enabling significant savings in terms of energy costs.

Practical calculation example

An example from the practice: If you install a floor heating with 20 cm pitch in a 40 square meter room, you have to drive the heater with a flow temperature of 40 degrees Celsius, the return temperature is 35 degrees Celsius. However, reducing the installation distance to only 10 cm tube spacing, one can, in order to achieve the same room temperature, work with much lower flow and return temperature, namely at 36 and 30 degrees Celsius. This reduction means a clearly measurable saving in electricity costs. Therefore, the pipe spacing is of decisive importance for energy efficiency.

Which room temperature is desired for underfloor heating?

The perceived as pleasant temperature, which is to give the floor heating, is an average of 29 degrees Celsius surface temperature in the living area in the bathroom, 33 degrees Celsius surface temperature ideal. This corresponds to a room temperature of about 20 to 22° C. These temperatures were determined in long-term studies that included human physiology and were used to create a consistent standard. Even with underfloor heating, which were already known in antiquity, especially with the Romans, but were only rediscovered, were "teething troubles" eradicate. But the modern underfloor heating system ensures large, pleasantly evenly distributed heat throughout the room with optimal utilization of the required energy and therefore not only works efficiently, but also reduces costs.
